  Basic bottle cast measurements (depth, temperature, salinity, oxygen, 
  density, potental temp., etc.). 
   
  NOTE:  J. Murray has flagged the CTD up cast, bottle trip variables  
  (Marker temperature and Marker salinity) as being suspect and should not 
  be used.  Selected down cast CTD temperatures and salinities replace these  
  variables.  However, if there is interest in the marker temperatures and 
  salinities a file containing these variables is available from the 
  data management office. 
   
  qflag = quality flag - J. Murray identifies stations with a * 
        as those having problems with the data 
        reported at that level. (mis-trips, suspect salinity, etc).
